Gear shift lever with damping device of a vehicle

Abstract

A gear shift lever is provided with damping device of a vehicle. The damping device damps the returning of a reverse gear blocking element in the axial direction of the gear shift lever into a blocking position. For this, the damping device has a first rigid ring element in the axial direction of the gear shift lever, which surrounds the gear shift lever and has projections distributed on the periphery in axial direction. In addition, the damping device has a second rigid ring element, which has recesses in the region of the projections of the first ring element. On the reverse gear blocking element and on the gear shift lever, radial shoulders are arranged, against which the two rigid ring elements support themselves axially. Between the first and the second rigid ring element a rubber-elastic ring element is arranged which is deformable in a rubber-elastic manner between the projections of the first rigid ring element and the recesses of the second rigid ring element on the returning of a reverse gear blocking element.

What is claimed is: 
     
       1. A gear shift lever for a vehicle, comprising:
 a reverse gear blocking element configured to turn in an axial direction of the gear shift lever into a blocking position; 
 a damping device configured to dampen when the reverse gear blocking element is turned in the axial direction of the gear shift lever into the reverse gear blocking element, 
 a first rigid ring element of the damping device in the axial direction of the gear shift lever that surrounds the gear shift lever and comprises projections distributed on a periphery in the axial direction; 
 a second rigid ring element comprising recesses in a region of the projections of the first rigid ring element; 
 radial shoulders are arranged on the reverse gear blocking element and the gear shift lever against which the first rigid ring element and the second rigid ring element are supported axially; and 
 a rubber-elastic third ring element is arranged between the first rigid ring element and the second rigid ring element that is deformable in a rubber-elastic manner between the projections of the first rigid ring element and the recesses of the second rigid ring element on returning of the reverse gear blocking element. 
 
     
     
       2. The gear shift lever according to  claim 1 , wherein the reverse gear blocking element is pre-stressed in a spring-elastic manner in the axial direction of the gear shift lever after engaging of a reverse gear. 
     
     
       3. The gear shift lever according to  claim 1 , wherein the reverse gear blocking element is a rigid, single-piece reverse gear stop block that surrounds the gear shift lever beneath a sleeve, which covers an opening of the gear shift lever of a gear-changing console. 
     
     
       4. The gear shift lever according to  claim 1 ,
 wherein the gear shift lever comprises an unblocking lever for a reverse gear that holds the reverse gear blocking element in a first position for blocking a reverse gear shift channel in a gearshift housing in the blocking position, and in a second position unlocks the reverse gear blocking element and releases the reverse gear shift channel in the gearshift housing under spring-elastic pre-stressing of the reverse gear blocking element. 
 
     
     
       5. The gear shift lever according to  claim 1 , wherein the first rigid ring element and the second rigid ring element have a hardening plastic. 
     
     
       6. The gear shift lever according to  claim 1 , wherein the first rigid ring element and the second rigid ring element have a fiber-reinforced plastic. 
     
     
       7. The gear shift lever according to  claim 1 , wherein the first rigid ring element is an integral component of the gear shift lever and the second rigid ring element is the integral component of the reverse gear blocking element. 
     
     
       8. The gear shift lever according to  claim 1 , wherein the rubber-elastic third ring element is an O-ring of an elastomer. 
     
     
       9. The gear shift lever according to  claim 8 , wherein in a damping phase on returning into the blocking position of the reverse gear blocking element, a rubber-elastic ring element is squeezed together and bent axially several times. 
     
     
       10. The gear shift lever according to  claim 1 , wherein the projections comprise rounded cams extending axially in a direction of an axis of the gear shift lever. 
     
     
       11. The gear shift lever according to  claim 1 , wherein the first rigid ring element and the second rigid ring element comprise undulating elevations and depressions extending axially in a direction of an axis of the gear shift lever, which engage each other and bend the rubber-elastic third ring element several times that is mounted there between, whilst maintaining a inner radius of a rubber-elastic ring element.
